FEATURES

Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.For controllable mechanical energy saving ventilation systems.Heat recovery minimises ventilation heat losses.Control of air exchange for creating comfortable indoor microclimate.Compatible with round Ø 160 to 400 mm air ducts.

DESIGN FANS

The casing is made of double-skinned aluzinc panels, internally filled with 20 or 25 mm mineral wool layer for heat and sound insulation.The casing has fixing brackets with vibration absorbing connectors for easy installation.The spigots for connection to the air ducts are located at the side of the unit and are rubber sealed for airtight connection to the air ducts.The service panel ensures easy access to the internals for cleaning, filter replacement and other maintenance operations.

High-efficient external rotor EC motors and centrifugal impellers with backward curved blades are used for air supply and exhaust.EC motors have the best power consumption to air flow ratio and meet the latest demands concerning energy saving and high-efficient ventilation.EC motors are featured with high performance, low noise level and totally controllable speed range.Dynamically balanced impellers.

HEAT RECOVERY AIR FILTRATION

The unit is equipped with a plate cross-flow (KOMFORT EC DE400/700/1100) or a plate counter-flow (KOMFORT EC DE2000/4000) aluminium heat exchanger for heat recovery. In the unit condensate is collected and drained to the drain pan under the heat exchanger.
The air flows are completely separated in the heat exchanger. Thus smells and contaminants are not transferred from the extract air to the supply air.Heat recovery is based on heat and/or humidity transfer through the heat exchanger plates. In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes ventilation heat losses and heating costs respectively.In the warm season the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. That reduces operation load on air conditioners and saves electricity.

FREEZE PROTECTIONThe electronic frost protection system based on bypass and heater is used to prevent the heat exchanger freezing in cold seasons. The bypass damper is opened and the heater is turned on automatically according to the feedback from the temperature sensor. Cold intake air passes by the heat exchanger and is warmed up to set temperature in the heat exchanger. Synchronously extract air that passes by the heat exchanger is used for its defrosting. After a freezing danger is over the bypass damper is closed, the heater is turned off. The unit reverts to the normal operation mode.

The built-in G4 supply filter and G4 extract filter provide air filtration.The F7 supply filter (specially ordered accessory) may be used for efficient supply air filtration in KOMFORT EC DE400/700/1100 units.

CONTROL AND AUTOMATION

The unit incorporates an integrated control system with a wall-mounted control panel and a sensor display.
The standard delivery set includes a 10 m cable for connection of the unit and the control panel.Automation functions:

  • Activating/deactivating the unit.
  • Setting required speed for the supply and extract fan for the unit air flow control. Each speed is individually adjusted during set-up.
  • Automatic heater activation/deactivation and smooth heat output control. Heater overheating protection. Cooling of the heater at the end of the heating cycle.
  • Opening/closing the bypass damper for summer ventilation.
  • Setting and maintaining room or duct air temperature.
  • Timer activation/deactivation and set-up.
  • Setting day- and week-scheduled operation of the unit.
  • Operation control on feedback from FS1 duct humidity sensor (available separately) or on the humidity sensor in the control panel.
  • Filter clogging control.
  • System shutdown on signal from the fire alarm panel.
  • Controlling supply and exhaust air dampers (to be ordered separately).
  • Cooler control (available separately).
AIR HEATER

The unit is equipped with an electric heater for operation during cold seasons at low outside temperature.The integrated electric heater is activated to warm up supply air flow if set indoor air temperature may not be reached by means of heat recovery only.Smooth heat output control ensures automatic supply air temperature maintaining.Two integrated overheat protection thermostats, one actuated at +60 ° with automatic restart and the other one actuated at +90 °C with manual restart.

  
MOUNTING

Ceiling mounting with fixing brackets.The correct mounted unit must provide free condensate collection and drainage as well as good access for servicing and filter replacement.Access for maintenance:

  • KOMFORT EC DE400/700/1100: on the right or left side panel.
  • KOMFORT EC DE2000/4000: on the bottom.
